REPRODUGING DEVICE.

SPECIFICATION forming part of Letters Patent No. 637,262. dated November 21, 1899. Appunti@ nea october 29,1898'. sensi No. 694,939. (No model.)

To all whom it may concern: l

Be it known that I, ARTHUR E. JACOBS, a citizen of the United States, and a'resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Reproducing Devices, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in mechanism for accurately copying letters or other designs` in facsimile or modifying the size or general proportions to any predetermined degree.

I exemplify my invention'by means ofthe accompanying drawings, as hereinafter described,and I specifically distinguish the same in the claims.

In the accompanying drawings, Figure 1 is aplan view of the device embodying my invention. Fig. 2 is a perspective view of a portion of the device, showing the manner of attaching the links through which the various changes of movement are effected. Fig. 3 is a detail of the frame supporting the spacingdial. Figs. 4, 5, 6, and 7 are views of letters formed by the device. Fig. 8 shows a word printed by the machine. Figs. 9, 13, and 14 show a design modified in shape and proportions by the device. Fig. is adetail of the copy-plate. Fig. 11 is a table of figures employed in using the spacing instrument. Fig. 12 is a detail of one of the graduated arms.

In the figures, 1 represents a bottom plate upon which all the Working parts of the device are mounted. l

2 is a draftsmans straight-edge, such as the tongue of a T-square, upon which the plate rests and upon which it is adapted to move longitudinally. This plate is provided with a recess 3, in which is placed the model or copy-plate 4, containing the design, which is followed by the tracing-point 5 of the machine in reproducing the design. The bottom f plate is provided also with the slots 6 and 7, placed at an angle to each other, the purpose of which will be described farther on.

8 is an upper plate adapted to move freely over the bottom plate and provided with adjacent rectilinear edges 9 and 10, parallel to the slots 6 and 7 in the bottom plate. Upon this upper plate is securely pivoted at 11 the copying pen or pencil 12, which moves freely with the plate.

'Movably pivoted in the slots 6 and 7, at theirinner extremities Y, are the graduated arms 13 and 14, which are pivotally united at their intersecting point at l5, one of them be- Y ing extended to form a handle 16, by which the arms are operated. At this point of union l5 the tracing-point 5 is placed,which follows the outline of the design. The graduations of the arms are marked by pin-holes 17, in which are placed pins 18, which bear against the rectilinear sides of the upper plate and force it to move with the arms in Whatever direction they may move, and hence trace a corresponding figure with the reproducingpoint 12.

In order to obtain the universal or floating movement desired for the upper plate and attached tracing-point and at the same time to support Vthem securely, I have adopted the peculiar construction shown in the drawings, where 19 is an intermediateplate orbar placed between thefixed bottom and upper floating plates by means of sets of links 20'and 2l. One set of these lin ks is pivotally attached at onev end to the under side of the intermediate plate and at the other end to the lower iixed plate, and the other set oflinks is pivoted at one end to the upper side of the intermediate plate and to the lower side of the floating plate. The sets of links are placed transversely to one another, and it will be seen that by their use in connection with the intermediate plate parallel movements al'e 0btained transversely and longitudinally of the instrument, thus affording a universal movement in all directions to the iioating plate and tracing-point.

It will be seen by reference to Fig. 2 that the links 2O pass under the lower plate, to which they are pivoted at 22, and the links 21 are pivoted to the under side of the upper plate at 23, thus preventing one pair from interfering with the other or withjthe movement of the auxiliary plate. 1

A spring 25 serves to normally. throw out the upper plate toward the point of Aunion .of the arms, and hence forces-the rectilinear edges always into engagement with the pins 18 when the plate is pressed back by hand in following the copy, thus permitting the plate to follow with the greatest precision every movement of the pins.

In operating this device it will readily be seen that the forms and all proportions of the letters can be changed at will by altering the position of the pins 18 in the graduated arms 13 and 14. For instance, if the pin iu one of the arms is placed near the pivotal point Y the movement communicated to the plate 8 by that arm will be less than when placed far from the pivotal point, and vice versa, and if one pin is placed farther from the point than the other it will move the plate proportionally farther in that direction than in the other. To make a letter similar in proportion tothe copy, both pins are placed equally distant from the pivotal points in the arms. To make a tall and thin letter, as in Fig. 5, the pin 18 in the arm 13 is placed near the pivot, so as to communicate but little movement to the plate and copying-pen, while the pin in the arm 14 is placed at a distance from the pivot, so as to make the height of the letter greater than the width. As many points in the graduation may be made as will afford all the variations in size and proportions that may be desired.

In Figs. 4 to 7, inclusive, are seen four variations of one letter.

In Figs. 9, 13, and 14 is seen a design for a dish or jug, as for a dinner-service, varied to adapt it to the different uses of table or other ware, one design, as a, being taken for a model and the others taken from it, as b and c.

` In Figs. 1 and 3 is shown a movable dialplate 30, which slides freely upon the tongue 2 and by means of the cross-bar 3l and side strips 32 is maintained in the close vicinity of the plate 1. This dial-plate is graduated upon one edge at 33 and provided with a pivoted pointer-arm 34, the pointer being grad uated similarly to the arm 13, before mentioncd, which determines the width of the letter. A link-rod 35 connects this pointer-arm with a graduated scale 36 upon the neighboring edge of plate 1. The graduation in these parts is indicated by pin-holes, into which the extremities of a link 35 are placed. The object of this device is to provide means for spacing the letters accurately when composing a word or line of words, since the letters may vary greatly in width and proportions, and hence the distance from center to center of the letters in a printed word varies also. To facilitate the use of this portion of the instrument, a table (shown in Fig. 1l) is employed in the following manner: The letters of the alphabet are printed at the side and across the table. Under each letter is a figure representing the space between it and the letter of the column at the left, as indicated on the dial. For instance, if the last letter printed is O and the next letter is to be an A the figure under A in the C column is 33. The pointer, normally placed at O,

is then moved to 33, when the instrument is in position to print the letter A.7 Before moving the pointer from O the link 35 should be placed in the index-finger at the same number as the one in which the pin 18 is inserted in the arm 13, since the movements of this arm decide the width of the letters, and the space between letters should be determined by the movement of this arm.

To assist in accurately placing the removable copy-plate 4it is provided with a notch 40, adapted to register with the projection 41 on the plate 1, and is removably secured in place by means of the spring 42.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
